人禍糧食危機

全球糧價急升，食品價格暴漲，大米兩個月內升了七成半，小麥一年內升了百分之一百二十．發展中及第三國家首當其衝，直接令非洲，亞洲及美洲出配暴亂．糧價急升正引發一輪人道危機及政府動盪．但這埸危機的主因由”人禍”引起．石油價格高企，早前有研究提出由玉米提煉乙醇來代替汽油，最後因污染及經濟兩大問題而未能持續發展，現在出現的糧食危機，問題在於早前大量稻田變成玉米田，玉米有價，農民改轉種植玉米，在中國等國家更不惜伐木做田，直接令稻米的產量減少，引至目前的糧價急升的主因之一．其次是商家的炒作，本來屬於冷門的糧食，變成了炒作的本錢，美元貶值，游資充斥，炒家不斷推高商品期貨，商品價格上升得比美元貶值為快．糧食供應本來有點不足，經過商品炒家和衍生工具的連番炒作，變成奇貨可居，商品市場的設計本來是為了紓緩價格變動的衝擊，現在經過游資翻雲覆雨，反而令價格矛盾化。

Keep matters for a time in suspense

Admiration at their novelty heightens the value of your achievements. It is both useless and insipid to play with your cards on the table. If you do not declare yourself immediately, you arouse expectation, especially when the importance of your position makes you the object of general attention. Mix a little with everything, and the very mystery arouses veneration. And when you explain, don't be too explicit, just as you don't expose your inmost thoughts in ordinary conversation. Cautious silence is the sacred sanctuary of worldly wisdom. A resolution declared is never highly thought of---it only leaves room for criticism. And if it happens to fail, you are doubly unfortunate. Besides, you imitate the divine way when you inspire people to wonder and watch.

Do not always be joking！

Wisdom is shown in serious matters, and is more appreciated than mere wit. He that is always ready for jests is never ready for serious things. Jokers resemble liars in that people never believe either, always expecting a lie in one, a joke in the other. One never knows when you speak with judgement, which is the smae as if you had none. A continual jest soon loses all zest. Many get their reputation for being witty but thereby lose yhe credit for being sensible. Jest has its little hour, seriousness should have all the rest.
